help...

i have am trying to add 2 new SATA drives (SAMSUNG 1.5TB SATA HD154UI) to my system (compaq SR1910NX, CPU upgraded to Athlon 64 X2 4600+, 4GB memory).

the system originally came with 1 SATA drive installed, running windows XP on it, and it is running fine. (WD 120GB drive, not sure the model).

the motherboard (asus A8N-LA) has 2 SATA controllers, 4 total SATA ports, 0-3. the WD-120GB drive is installed and running on SATA port 0.

when i installed the 2 new samsung HD154UI drives in SATA ports 1 and 2, they are not recognized by the BIOS, and obviously not by windows XP. the BIOS reports the 120GB drive on SATA port 0, and ports 1,2, and 3 empty.

i have verified the power and sata cables, by trying all the new cables on the 120GB drive, and they work fine.

i have verified all 4 SATA ports by installing 120GB drive in each one, and it is detected and operational.

i am reading that there may be issues with 1.5 vs. 3.0 transfer rates? i am also reading that there may be issues with my motherboard recognizing large drives?

anybody have any ideas?
 
Hi, I doubt there will be an issue with the 1.5Gb/ or 3Gb/s Bus frequencys as all they are is a bus cap (limit) which non of your drives will ever cap.

I can suggest a bios update incase the motherboard's sata controller doesn't support/detect 1tb of space or over. If no joy after the bios update the drives are at fault.
 
turns out that the drives were bad. (both of them!).

i returned them, and got seagates, which plugged and played immediately, with the power and sata cables i had already installed for the samsung drives.
